Still .anf additional object-.is 'to provide a .novel burner structure.I

Witlnthese andro-ther Aojrij'ec'ts in view, my

invention: consists in @the-,-c`onstruotion, ar-

rangement :and ,Combination [of the various partsgoffinywdeviceL-wherebytheects contemplated are attained, as hereinaftermore fully setforth, pointed out in my claims, and illustrated in theaccompanying drawings, in which:

Figure 1 shows a vertical, central, sectional view through an oilburning furnace embodying my invention.

Figure 2 shows a detail, sectional view taken on the line 2-2 of Figure1.

Figure 3 is a detail, sectional View taken on the line 3-3 of Figure 1.

Figure 4 is a detail, sectional view through a portion of the bottom ofthe furnace; and

Figure 5 shows a detail, sectional view through a slightly modified formof the bottom.

In the drawings herewith, in which one form of my invention isillustrated, I have used the reference numeral 10 to indicate generallythe casing of the furnace or stove.y

12, 'which may be made "of Alire clay,='a1s Vshown for instanceinFigures land 4- or as shown at 13`-1n Figure 5, where the-fire`boXvrbottom 1s made lofgrate iron.

V1"Vzll'here the casing is -madefof thin steel,

for instance, I preferably-line it' above the bottom 1l forarsubstantialdistance 'withfire brick' 1:4. v

The casijn'gmay bemade* Ofany L'suitable material,V cast 3 firo'n orotherwise, that f is adaptcd'forithe purpose. Y

' I-:providethe bottom -12401 13,as the )case K4may be, mordertoprotectthe concrete ibot- -toinl 11 from the intense heaftfwithin tlrefire box Yportionof thel casing. y

The casing 10 is providedA with V-a door 15 4in its side wall to permitIreadyaccesstofthe interior o'f the furnace .or `stove.

"Mounted-"in-the bottomfofithe'stoveeis a receptacle or reservoir 1G,the lower---endif 'which projects 'below 'thebottorn11l alndisjnov'idedwith ascrewcap 117 for clean-out purposes. y l

Connected Viwith 'the cap.` L17 by a visuitable Extendingupwardfronifthe upper' end :the reservoir or "receptacle 1G` is a short"pipe-19. on which is a' T--niplple20- Screwed The upper face or surfaceof the bottom l 12 is concave as at 23. The same configuration is foundin the modiiied forni of the bottom shown at 13 in Figure 5.

Connected with the nipple 2O is a drain pipe 24 extending to a pointoutside the casing 10. The drain pipe 24 may lead to the sewer or to anysuitable receptacle to take care of overflow.

An air supply pipe 25, the size of which is determined by the size ofthe furnace or stove and by the heating problem involved, enters thecasing 10 at the top or any suitable point and has a portion eX- tendingdownwardly and terminating just above the spreader flange 22. One ormore hot air pipes 26 may lead oif from the upper portion of the casing10. Braces 27 may be provided for the pipe 25, if desired.

It will, of course, be understood that suit-Y able control valves areprovided for the fuel and that the pipe 19 is connected with a source offuel supply.

In the practical use of my improved furnace or stove, the oil, such `askerosene for instance, is supplied through the pipe 19 to the reservoir16 and will then flow upwardly to the burner nozzle. f

A small amount of oil may be ignited in the concave portion 23 of thebottom 12. After it is burned a short time, the conductivity of thebottoms 12 and 11 is such as to cause a gas to be generated, so thatwhen the flow of oil is properly regulated only agas will be burned.

The air flowing in through the pipe 25 will be directed downwardlyagainst the open end of the nozzle and the spreader flange 22 and theflame will thus be directed downwardly and outwardly.

The flame will thus be properly spread and the gas will burn with anintense heat.

The concrete bottom 11 is protected against overheating and consequentdisintegration by the bottom 12 or 13 as the case may be.

The amount of heat generated can, of course, be regulated by controllingthe flow of fuel.

In case the fire should go out or in case the fuel should be permittedto flow to the nozzle when the fire is not burning, the furnace or stovewill not overflow 4and be flooded with oil, but the oil will be held bythe concave portion 23 and will flow back through the nozzle 21 to thedrain pipe 24. The drain pipe 24 is provided with an upward bend 28,which stands at a height practically Hush with the upper discharge endof the nozzle 21 for thus preventing the flooding of the furnace orstove.

It will, ofcourse, be, understood that the size of my burner may bevaried as may be desired; that the size of the pipe 25 is determinedbythe number of cubic feet of rooms to be heated; and the size and numberof the pipe or pipes 26 is determined by the heating problem.`

The device mayv be readily made in the form of a furnace or to serve asa heating stove. Any material suitable for the pur pose may be employedin any of the parts of my improved oil burning furnace orstovestructure, and I intend to cover by the claims of my patent anymodified forms of structure or use of mechanical equivalents oremployment'of a variety of material or changes in shape or size, whichmay be included within the scope of such claims.

I claim as my invention:

In a structure of the kind described, a casing, a bottom therefor, afire box bottom above said first bottom, having a concave upper surface,a burner nozzle located within such concave portion, to discharge at a.point below the periphery thereof, a reservoir below said nozzle and incommunication therewith, located substantially below the upper surfaceof said fire box bottom and belowv thel point of combustion ofthe burnerso as to be free from sufficient heat to disintegrate the fuel, but tobe warmed duringthe operation of the device.
